" 55.यदि "tan theta+sec theta=x," Then prove that "sin theta=(x^(2)-1)/(x^(2)+1)

If sec theta+tan theta = x , prove that sin theta= (x^2-1)/(x^2+1)

If sec theta-tan theta=x then prove that cos theta=(2x)/(1+x^2)

tan theta+sec theta=x show that 2tan theta=x-(1)/(x),2sec theta=x+(1)/(x) hence prove that sin theta=(x^(2)-1)/(x^(2)+1)

If tan theta+sec theta=x" show that 2 tan "theta=x -1/x, 2 sec theta=x+1/x. Hence show that sin theta=(x^(2)-1)/(x^(2)+1)

If sec theta=x+(1)/(4x), then prove that sec theta+tan theta=2x or (1)/(2x)

If sec theta=x+(1)/(4x), prove that :sec theta+tan theta=2x or ,(1)/(2x)

If x=a sec theta+b tan theta and y=a tan theta+b sec theta then prove that x^(2)-y^(2)=a^(2)-b^(2)

If x=a sec theta,y=b tan theta, then prove that (x^(2))/(a^(2))-(y^(2))/(b^(2))=1

x = a sec theta + b tan theta and y= a tan theta + b sec theta. Prove that x^(2)-y^(2) = a^(2)-b^(2) .

If x=a sec theta+b tan theta and y=a tan theta+b sec theta, prove that: x^(2)-y^(2)=a^(2)-b^(2)
